General Service Lamps (GSLs)
In August 2020, the Director of the Governor’s Office of
Energy adopted regulation R100-19 pursuant to NRS 701.260 as amended under AB
54 (2019). Regulation R100-19 sets a minimum standard of energy efficiency of 45
lumens per watt of electricity consumed that must be produced by General
Service Lamps sold in Nevada on and after January 1, 2021.
What are General Service Lamps?
General Service Lamps (GSLs) refer to lighting applications
traditionally served by general service incandescent lamps (GSILs), also known
as "A-type" bulbs.
The majority of lighting in a residence is covered under the
new standard and definitions.
Description and images of some commonly covered bulbs are
below. For detailed information on covered bulb specifications under the
updated standard click here.
Included in the new standard are, General Service
Incandescent Lamps (GSILs), Compact Fluorescent Lamps (CFLs) and General
Service LED Lamps. These are the most commonly used lightbulbs, generally the pear-shaped
bulbs. Common applications are table side lamps and light fixtures that are
If each resident replaced all of their inefficient lighting
with the updated standards, Nevada residents could save over $81 annually on
their utility bills, according to a report published by the Appliance Standards Awareness Project (ASAP).
|Traditional incandescent bulbs waste a lot of energy as heat in order to create light. They last about one year, on average
|Improved halogen incandescents use up to 30 percent less energy than traditional light bulbs and can last three times as long.
|Curly compact fluorescent bulbs use up to 75 percent less energy than traditional bulbs and can last for 10 years. But they can be slow to brighten and have a colder light quality.
|LED bulbs, or light emitting diodes, use up to 85 percent less energy than traditional bulbs and can last for 25 years, without some of the drawbacks of compact fluorescents.
